Abstract

A case of a giant intracranial aneurysm (GIA) with a blind sac on the left middle cerebral artery (MCA) accompanied by mural thrombosis is described. A 62-year-old male presented with headache and motor dysphasia. Magnetic resonance imaging and digital subtraction angiography revealed a GIA that arose from the proximal MCA. The M2 segment of the MCA was not visualized due to intramural thrombosis. The patient was treated with an extracranial-intracranial arterial bypass and trapping of the aneurysm. Literature relevant to the management of this rare lesion is reviewed and discussed.
